Many of the low-quality posts tend to surface as there aren't sufficient information in there (like elaboration, examples, anecdotes, sample situations, etc).
Since IPS is moving towards having anecdotes and experiences in all of the answers here, I feel it is a good idea for the "Recommend Deletion" button for the review queues to have an option which says "Your answer is not sufficient enough. Please add more information or personal experiences in your answer to support your points." or something along those lines.
Also, would it be a good idea for the system to auto-generate the comment to the answer so that the user can improve on their answer? I've seen several occasions where more experienced users on this forum has had to type out the comment, such as in this answer here, though there are many other instances where I see such comments. Maybe an auto-generated comment once the "Recommend Deletion" button has been pressed would be great for this purpose?
P.S. this is my first post on meta, please guide me along if I have mistaken the use of the meta.
